The advantage, brilliantly revealed.

FairfieldNodal’s depth imaging capability is built around a proprietary and fully integrated set of tools, workflows and algorithms that are purposefully designed to take advantage of the wide azimuth illumination that node acquisition provides.

Acquisition to final image: experts at every step.

Our expertise in node technology extends beyond acquisition. From high performance computing to highly optimized imaging algorithms our processing and research teams are committed to providing the best technical solution to complex imaging and reservoir management problems.

Our time and depth migration algorithms include:

Kirchhoff PSTM – isotropic and anisotropic

Kirchhoff PSDM – isotropic and anisotropic

Common offset

Offset vector tile (OVT)

Wave Equation (WEM) – isotropic and anisotropic

Output angle domain common image gathers (ADCIG)

Reverse time migration (RTM) – isotropic and anisotropic

Model updates with ADCIGs

Subsalt Imaging in the Delaware Basin.

2D line extraction from FairfieldNodal’s Delaware Basin multi-client program. Ray bundles, projected from a deep horizon, become distorted as they encounter a near surface velocity inversion caused by a thick accumulation of anhydrite.

PSTM vs. Anisotropic PSDM

PSTMPre-stack time migration does not adequately resolve the complex ray bending. PDSMThe PSDM image is more focused in the prospective section below the anhydrite. Beyond providing a superior image, PSDM has the added benefits of providing flatter pre-stack depth gathers making it easier to separate mutiples, attenuate noise and preserve amplitude, offset and azimuthal information.
